What is the minimum level one can feasibly reach the 3rd "World of the Recycled Vessel" challenge chamber in Nier? I ask because the 3rd chamber of the DLC is supposed to have enemies that have a higher drop rate of Titanium Alloy than the robots in the Junk Heap.

At the time of asking, I am around level 13 and die in 2 hits in the first challenge chamber.
